Concrete drilling system and related methods

A drilling tool including:

• a motor for turning a drill bit;
• said drill bit being mounted in a frame, said frame having at least one piston to control the distance between said drill bit and a drilling surface, said frame further including a base with at least one sealing element to form an air tight chamber, said air tight chamber including a port attached to a vacuum source to secure said frame to said drilling surface and to position said drill bit at a selected site for drilling into said drilling surface.

A portable base for a drilling machine including:

• a power control system;
• an air pressure control system attached to the drilling machine;
• and a recirculating water flow control system to recirculate water from a water storage apparatus through a drill bit attached to the drilling machine.

Apparatus for drilling holes, including:

• a portable frame selectively positionable adjacent a surface to be drilled;
• a drill mounted in a first portion of said frame, said frame having a second portion securable to the surface to be drilled, and means acting between said first and second portions for controlled articulation of said drilling device with respect to the drilling surface.

Apparatus for drilling holes, including:

• a motorized drilling device mounted on a first portion of a frame, said frame having a base portion securable to a drilling surface, said first portion and said base portion being slidably engaged with each other, and means acting between said first portion and said base portion to articulate said drilling device with respect to the drilling surface.

A drill bit for drilling holes, including:

• a shank portion having a first end and a second end, said first end engageable with a drill motor, and said second end configured to contact a drilling surface;
• said shank portion having a hollow bore therethrough exiting at said second end, said exit providing an opening at said second end;
• said opening providing means for creating an unobstructed hole in said drilling surface.
